Automatic Stabilisers

Government policies that aim to automatically stabilise short-term fluctuations in economic activity, with no change in policy.

Budget Deficit

Occurs when government spending is greater than tax revenue

Progressive Tax System

As someone's income increases, the proportion of income paid as tax increases.

Crowding Out Effect

If the government increases spending and runs a budget deficit, this will push up interest rates and crowd out some investment and consumption.

Multiplier Effect

An increase in injections in the economy results in a proportionately greater effect on aggregate demand.

Marginal Propensity to Consume (mpc)

The proportion of additional income that households spend on domestic goods and services.

Marginal Propensity to Tax (mpt)

The proportion of additional income that households pay as tax.

Marginal Propensity to Import (mpm)

The proportion of additional income that households spend on foreign goods and services.

Marginal Propensity to Save (mps)

The proportion of additional income that households save in banks.

Keynesian Multiplier

1/(1 - mpc) = 1/(mps+mrt+mpm)

Effect on AD

Effect on AD = Multiplier x Size of Injection
